Dear EMC-PSTC,
My company is currently designing a speaker system meant for ITE (that
is PC) connection.
The speaker requires external supply which the hardware team is looking
into using a AC/AC adaptor instead of AC/DC adaptor.
This AC/AC adaptor which steps down the 230Vac or 110Vac to the required
low voltage for the speaker supply.
A supplier of such AC/AC adaptor has said that their product complies to
EN60335-1 standards.
As I'm not familar with this standard, and need advice on the following
doubts.
1) Is this EN60335-1 equivalent to IEC 742 ?
2) Heard from a colleague (from his source) that EN 60335-2-207 should
be the standard ?
3) Was browing through the LVD Harmonised standard and unable to find
this 60335-2-207. Could someone advice what is this standard ?
4) Is this supplier statement of the AC/AC adaptor conforms to EN60335-1
sufficient? Or should this AC/AC adaptor meant for household &
electrical appliance required to fulfil EN60335-2-207 standard ?
5) Does EN60335-1 applicable to AC-AC adapter only ?
6) Are this standards (EN60335-1 and EN60335-2-207) still valid? Or it
has been obsolete/replaced?
7) Could this AC/AC adapter that complied with EN60335-1 be bundled with
ITE product meant for Home or Office use?
Looking forward to you advice.
Thanks in advance.
Regards
Koh
